The relatives of a rich old woman unsuccessfully try to have her declared insane, so they can divide up her money. To show them that there are no hard feelings, she invites them to her estate for the weekend so she can decide to whom she actually will leave her money when she dies. Soon, however, family members begin turning up dead.
